Rails - Render Ajax inside a loop - ruby

Question

I'd like to update several single table cell in my view with ajax.
Is there a chance to run the uptime partial several times during the loop?
Currently the loop iterates over all given records but the partial runs once.
def CheckUptimes
require 'net/ssh'
#username = "updater"
#password = "üqwlp+ß$2"
#cmd = "uptime"
#items = Item.all.where("(category = 'Ubuntu 14 LTS')")
#items.each do |ci|
#hostname = ci.name
begin
ssh = Net::SSH.start(#hostname, #username, :password => #password)
#uptime = ssh.exec!(#cmd)
ssh.close
#uptime = #uptime.strip
ci.update_attributes(:uptime => #uptime)
respond_to do |format|
format.html
format.js { render :partial => "uptime", :locals => { :id => ci.id, :uptime => #uptime } }
end
rescue
puts "Unable to connect to #{#hostname} using #{#username}/#{#password}"
end
end
end

If I understand well, I think you could save in two instance variables (Arrays) which hostnames were able to to connect and which not, and then in checkuptimes.js.erb you can show which ones are ok with render collection
Something like this
#con_ok=#con_ko=[]
#items.each do |ci|
#hostname = ci.name
begin
ssh = Net::SSH.start(#hostname, #username, :password => #password)
#uptime = ssh.exec!(#cmd)
ssh.close
#uptime = #uptime.strip
ci.update_attributes(:uptime => #uptime)
con_ok<<ci.id
rescue
con_ko<< ci.id
end
respond_to do |format| ## Not necessary ##
format.html
format.js
end
in checkuptimes.js.erb
$("#mydiv").html("<%= escape_javascript(render 'uptime', collection: #con_ok)%>");
in this example, the partial uptime will be rendered as many times as items contains #con_ok, with a local variable con_ok with the the item in the array (id)
